I’ve had this monitor for a year and a half. It is excellent. To this day I’ve had no issues, the picture is great and I use it for mainly gaming. 165 hz is great on a big display like this. 10/10!

I was extremely skeptical of this monitor. I’ve never heard of this brand. This was purchased for Battlefield 6 on the PS5. I noticed that my old eyes could respond better on my son’s gaming monitor than my 120Hz Samsung TV. So I started looking for a larger monitor. The low input lag, colors, brightness are all better than I expected. I have no idea how long this monitor will last, but at that price point, I’ll just get another.

Great bang for the buck. The only reason for 4 starts is because the circular section on the back of the DGLUX340 may look like an LED light, but it's actually just a decorative design and does not illuminate or have any functional lighting features.

With Covid hitting back in March my GF and I had to move from our offices to home. She works remote from her laptop at home connecting into her PC in the office. We found that remote desktop rearranges the windows every time when you disconnect/reconnect to the remote PC. One big monitor solved this and it works great for her day to day offices needs as well as home stuff. I game and at 100hz it's much better than the pair of dual 27" I used to use. I work with two laptops at home, one for work and the other personal. I have a Tripplite B004-DP2UA2-K KVM (IOGear GCS62DP is the same and cheaper, buy it) to handle the switching of two DisplayPort signals at 100hz and it works. I game on it daily and do all my remote server work with no problems. With the high resolution and large screen it works really well to have half a dozen remote sessions up and keep them all on the same screen. I did have one of my two monitors start to have a weird flicker in the lower left corner. It came and went, but wasn't too much of an issue until it wasn't. The weird flicker got more frequent and annoying, so I called support. 2 days later I'm swapping monitors and sending the bad one back. No issues with support at all, they rocked.

I'm still going to give this 5 stars because it would be a great monitor for SOMEONE. Just not me. My desk isn't huge, about 4 feet wide, 2.5 feet deep, monitor was LOOMING over me with how close I had to have it, even in the corner of the desk. Monitor is VERY bright. Brightness cannot be controlled with HDR on, and monitor looks horrible with HDR off. Looks OK with HDR on but extremely bright. When you turn HDR on the monitor's own setting for Brightness is grayed out. I do have a graphics card and computer that should be fine for this monitor, GeForce RTX 3060 12GB GDDR6, on a Lenovo Legion T5 Tower with AMD Ryzen 9 7950X. Even if there's some setting I missed and this can be dimmed with HDR, is still too big to use on a normal size desk. This monitor would probably be great for a budget gamer who wanted to play multiplayer games with 1 or more friends in person, with this set up in a living room or basement, so you could get 5 to 10 feet back from it. Mounted on wall would work and it comes with a universal stand adapter. Would also be good as a TV in a waiting room for a doctor's office, or for displaying frequently updating data (like flight times) somewhere in public. But I returned it.

The item arrived used, even though the description made no mention of prior use. The monitor already had greasy fingerprints on it, as shown in the photos, and was damaged. In addition, the package was missing the brackets needed to attach the display to its stand. Not only was the item used, but it was also defective. I had been waiting for this delivery, it was delayed, and I am very disappointed to have received such a poor-quality product.

Amazing monitor size and resolution for the price. The sheer size is crazy: almost like stacking two ultrawides on top of each other. This is an absolute work productivity beast (endless rows on spreadsheets) and is very usable for many games. In particular, bright color games like Assassin's Creed and Horizon Zero Dawn play very well. Same goes for many RTS games. This monitor does not have OLED black levels and color pop so it noticeably struggles with dark games like Last of Us and Resident Evil. I put it on a desk mounted stand for height and depth adjustment. Since it is so big, everyone will want different viewing distances and angles. The provided stand is well made but rather large and rigid (no height adjustment). The power cord is a little short but I had many of those saved up over the years. There are very few curved options at this size. You get a lot of monitor for the price. I am very happy.

First, I was hesitant to purchase this item because I didn’t know the brand. After working through a communication issue with their staff, I have absolutely no concerns about whether they would stand by their products and services. I was looking for a large, curved screen to replace 3 screens. I have a MacBook M2 that I use for programming. This was (by far) the largest 16:9 curved monitor I could find, and the price was half of the others I was considering. This monitor fills my needs very well: - With an HDMI connection, the text is clear. - The flexibility of one large monitor over multiple smaller monitors is a game-changer. - The 16:9 aspect ratio allows me to see almost 100 lines of text on one screen, and compare documents side-by-side at full-width. - The curve really does make a difference when the monitor is relatively close.
